This is very cute! I think it's possible that this behavior was present in the ancestors of birds, but really, nobody knows for sure. What is the species of bird that puts flowers in its nest? I do know a lot of bird species like to "decorate" their nests, but I don't know the species that uses flowers. I like the green feathers, including the stripes on the "wings" and the spots on the legs. I like the sun shining through the trees too.
